ok sorry. I just realized that it was automatic. I thought you did something to get it because I never fully checked the tabs on the synthesizer instrument. The reason I thought you did something to get it is because for some reason, I thought that this tab could be accessed with every instrument. You did a wonderful job with "all stars" though.
Not completely certain of what you mean but I think I get it. A synthesizer tab shows up when I used the Synthesizer, instrument. All I did was duplicate it and rename the instrument so If I need said instrument in the future but with a different sound I can just easily duplicate it again. Or basically I just copied and duplicated the regular synthesizer.
